HARRY S. HART, OF CHICAGO, ILLINOIS, ASSIGNOR TO RODGER BALLAST CAR COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF MAINE.

UNDERFRAME FOR RAILWAY-CARS.

To all whom it may concern:

Be it known that I, HARRY S. HART, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Underframes for Railway-Cars, of which the following is a specification.

The object of my invention is to provide a draft sill of improved construction, and improved means for attaching the same to the body of the car.

Further objects of my invention will appear from the following specification and claim.

Referring to the drawing Figure 1 is a sectional elevation of part of a car constructed in accordance with my invention and showing the draft sill. Fig. 2 is a plan view of the parts shown in Fig. 1.

In the drawing, I have illustrated my invention as applied to a car provided with a hopper bottom, but in certain aspects my invention is not restricted to a car of that type, being equally adaptable for use with other cars.

In the form of my invention herein illus trated, the draft sill consists of two channel beams 11 and 12. Instead of terminating at the body bolster, the draft sill passes between the upper and lower members 1 and 2 -of the bolster, and at its inner end is attached to some of the structural parts of the car. In the present instance, the draft sill is shown attached to the side of the hopper 13 by means of angle irons l5 and 16. The draft sill is also attached to the Specification of Letters Patent.

body bolster by means of rivets and to the end sills.

By means of the structure described, the draft sill is secured to the various parts of the car structure in such a manner as to make ample provision for the shocks and stresses to which it is subjected.

The manner of stiffening the body bolster illustrated in the drawing is especially adapted for use with a center sill of the structure above described. This stiffening consists of channel members 7 and 8 of a length equal to the distance between the angle beams forming the center sill. The webs of the channel members referred to extend transversely of the car and the upper and lower flanges of said members are secured to the upper and lower members, respectively, of the body bolster. The channel members 13 and 14 are placed between the members 7 and 8 and have their flanges secured thereto, as illustrated.

By this construction ample means are provided for withstanding the stresses at the truck bearing.

What I claim as my invention is In a car of the class described, a hopper, a draft sill extending from the end of the car to a point beyond the body bolster, said draft sill abutting directly against the hopper at its inner end and attached thereto, and a transverse beam above the inner end of the draft sill adjacent to the hopper.
